Which option is NOT a processing category for mailpieces?

• A. Outside Parcels
• B. Flats
• C. Letters
• D. Oversized Parcels

Answer: (D)

Processing categories in USPS operations are the main groups used to sort mail: Letters, Flats, and Parcels. Each category dictates how the piece is routed and handled by sorting equipment and staff. An oversized description refers to the size within the Parcels category, not a separate processing stream. So, there isn’t a distinct processing category called Oversized Parcels; it’s simply a size characteristic of Parcels. The other options align with the established processing categories—letters for small enclosures, flats for larger flat pieces, and parcels for packages of varying sizes—making Oversized Parcels the correct choice for what is not a separate processing category.
